The INTEGRAL-Swift Burst of 041219 (GCN 2866, Gotz et al, GCN 2874, Barthelmy et al.) had a time history that is rather rare: a precursor was followed by 200 sec of mostly quiet emission before a huge spiky outburst that lasted an additional 300 sec. This is one of the few events for which there have been simultaneous ground observations. It is the first event with simultaneous IR observations (GCN 2870, Blake and Bloom) and there has been a near-threshold detection in the optical (GCN 2889, Wren et al.). Given the large interest in this burst and the scientific value of combining the simultaneous gamma-ray and ground observations, we provide at the web site below the GRB041219 4-channel data (15-25 keV, 25-50 keV, 50-100 keV, 100-350 keV) for -341 s before to +558 s after the BAT trigger with 0.064 s resolution. Provided are figures for each energy band, the 15 - 350 keV energy band, and a text table of the data.
